| Abstract |
This study aimed to produce the torrefied biomass with high energy density for the solid bio-fuel application. Biomass wastes; coffee ground residue, sawdust and corncob, were mixed at the fixed ratio of 4:3:3 by weight. Central composite design was applied for experimental design with two independent factors: temperature and time for torrefaction. The optimum condition of torrefaction was investigated by response surface methodology. The severity factor in the term of process variables was represented to justify the response as weight loss, heating value and energy yield. Increase of severity factor reduced the energy yield, increased the weight loss and heating value of torrefied biomass. Compared to the raw biomass waste, the heating value of torrefied mixed-biomass waste was improved about 29.51 to 61.02%. The heating value and weight loss in biomass slowly increased as the severity factor increased up to 6.90 and then quickly increased when severity factor over than 6.90, resulted to the decrease of O/C and H/C molar ratio. From the optimal condition with severity factor of 6.32 at about 254C and 60 min, response in weight loss, heating value and energy yield, was 40.77%, 25.00 MJ/kg and 83.35 % and, respectively. This torrefied biomass will be further densified in the pellet form to meet the requirement of industrial sector. |
